Errors in new version

Following the latest update, I see this error:

Notice: Undefined index: content_owner in /wp-content/plugins/content-audit/content-audit-report.php on line 290

When I try to save the Content Audit options page, I get a white screen with these errors:

Notice: Undefined index: display_switch in /wp-content/plugins/content-audit/content-audit-options.php on line 29

Notice: Undefined index: mark_outdated in /wp-content/plugins/content-audit/content-audit-options.php on line 32

Notice: Undefined index: notify in /wp-content/plugins/content-audit/content-audit-options.php on line 35

Notice: Undefined index: notify_now in /wp-content/plugins/content-audit/content-audit-options.php on line 38

Notice: Undefined index: notify_authors in /wp-content/plugins/content-audit/content-audit-options.php on line 41

Warning: Cannot modify header information – headers already sent by (output started at /wp-content/plugins/content-audit/content-audit-options.php:29) in /wp-includes/pluggable.php on line 1210

I haven’t been able to test without other plugins or a different theme yet, but I can if that would help with troubleshooting. Love the plugin!
